List of Hybrids of European Orchids
You came across a hybrid name in literature,
and don't know which combination it means ?
Three hybrid types are distingushed, of which mainly the first two ones are theme of this list:
Base of this compilation are the books, magazines, and private orchid lists at my disposal. It will be continued permanently. Occasionally I check hybrid lists of web pages, too. In this context I want to thank Mr. Mathias Raschka, who infatigably searches the internet for orchid hybrids since years and makes his results available for the completion of this web page.
As usual both parents of the hybrid are mentioned in alphabetical order. The whole list is sorted alphabetically according to the first parent species, and because of its size the web representation is divided into several separate files. The intergenetic bastards appear behind the hybrids within a genus, at the end of the entries for the genus of the first parent species.
If authors of the hybrids are mentioned, then only the names of the original authors, who "coined" the name, not the names of persons who did recombinations later.
If you are looking for the correct citation of a hybrid with name of author and eventually recombinator as well as the corresponding original source, then the search function of the International Plant Names Index, which is available in the Web today, is better suitable. My list supplements it by delivering more literature and iconographic sources. If no source is mentioned at a hybrid combination it has in most cases been taken from the internet, and can usually be found there via search engines.
About 3000 hybrids are currently contained.
It's my private compilation, which lays neither claim completeness nor soundness.

I have been maintaining this list for more than fifteen years. Many earlier described hybrids are taken from the compilation in Sundermann's field guide (3. edition 1980), which has the problem that the author didn't distinguish between many closely related species. If known, I supplement these collective species with s.l. or s.str.
My compilation contains many synonyms of designated hybrids. On one hand the check of all the priorities under the today's closer definition of species would last several years, and I'm currently not intending to do it. On the other hand mentioning of synonyms is intended, in order to give their hybrid combination, and in many cases to refer to further literature about these, too.
Certainly one must assume that the literature about hybrids, and therefore also this compilation, contains many mis-determinations. Everybody knows how thoughtlessly the maddest speculations arise in the enthusiasm for an unusual finding. Nevertheless the compilation may be a useful reference, which e.g. may shorten some search for recent literature references about hybrids of European orchids. Hybrids, which are very doubtful according to today's view, are usually marked ('zh').
More primary hybrids seem to be possible than some are thinking, e.g. in 1999 the artificial generation of a hybrid between Ophrys x albertiana and Orchis fragrans was credibly published, of which photos are available again in the internet since short time. Today modern scientific methods as e.g. analysis of the genes can clearify doubtful cases, as the example of the 1988 published supposed hybrid Aceras anthropophorum x Neotinea maculata from Gargano is showing, which turned out as an atavistic Neotinea. Below there are some examples of unusual and atiavisic orchids which are no hybrids.
